Miley Cyrus Takes the Stage at Star-Studded Bash in L.A.

A day before the news of her parents' divorce broke, Miley Cyrus hopped on stage sporting a crop top, baggy pants and a fauxhawk and started dancing while Robin Thicke and Pharrell Williams performed their hit "Blurred Lines" at a Myspace party in Los Angeles. The guys didn't seem to mind, though: After her impromptu routine, Cyrus hugged both singers and earned cheers from the crowd.

The starlet – sans fiancé Liam Hemsworth – was just one of many stars at the Wednesday night party, a re-launch for the social networking site held at the El Rey Theatre.

Justin Timberlake, a part owner of the site, kept a low profile at the bash, hanging in the VIP area and chatting with pal Olivia Wilde. The actress also caught up with Glee star Dianna Agron for a bit, showing off her engagement ring and "looking giddily happy," according to an onlooker.
